Global optimality conditions for nonconvex optimization. (English) Zbl 0908.90243
Summary: We give an analytical equivalent for the inclusion of a set to the Lebesgue set of a convex function. Using this result, we obtain global optimality conditions (GOC) related to classical optimization theory for convex maximization and reverse-convex optimization. Several examples illustrate the effectiveness of these optimality conditions allowing to escape from stationary points and local extremums.
